The "Cat Eye" was high tech in the late 50's through the 70's. The Cat Eye was used for tuning transmitters with a visual aid to the sound output of the transmitter. They were used extensively on the Weather Facsimile Receivers I used in the Navy. USN 1965 to 1969.

I had several of these on some used test equipment I purchased. My parents' 1960 Scott tuner used a magic eye tube but it had two horizontal green 'bars' which expanded/contracted towards one another to indicate station tuning. These and nixie tubes are still fascinating marvels of consumer tube technology.

These are easy to find unused and are very common .6u5 6g5 are a little harder to find but still out there at many on line tube shops or ebay .

What did it cost,I built a tube type tuner kit from the fifties ,I found this kit in the seventies,it had a magic eye ,but it was a small skinny upright tube ,used for tunning the tube radio ,magic eyes come in several sizes ,I also had a old reel to reel with a magic eye .I love them they are very cool ,they seem to last a long time too

I have one in my 1937 Sparton radio. It still works but it has layers of dust and dirt on it. I'm not smart enough to understand electronics, but is it possible to make this old radio FM capable? Or should I just be happy my radio works?

scott FREE be happy that it works
Simular I think, but smaller used for old tape recording levels https://www.youtube.com/watch?v=Fw0si6Q_yUg and https://www.youtube.com/watch?v=K_VD6UF1SGQ Not sure about this one> https://www.youtube.com/watch?v=oHN2rWbaLew

Hi Mark, I have a EM84 Magic eye. I have used it before but now its glowing very low. Can you please suggest is its because of some voltage change or the tube is have some life time and after that it will glow less?
md10591 (10 months ago)
the tube is reaching his life end .
pankaj motiyar (2 years ago)
thanks for the reply it has dim over time. May be need to put some reverse high voltage to remove the Plate deposition.
Mark Furneaux (2 years ago)
It's like a CRT; it will dim over time. If it happened suddenly, check the voltage.

Mark, thank you for the video. I have a question if possible. You have connected the "Anode" (pin3) and "Target" (pin6) to +180V, and "Cathode" (pin8) to the "ground pin" coming from the power supply right? So power source's DC 180V's + is used by pin3, pin6 and 180V's ground is connected to pin8... Thanks :)
Emre Telci (2 years ago)
Thank you Mark.

You need a resistor (~1meg) in between the anode and the supply. Otherwise you will not be able to adjust the opening with the grid.

Du you have an ebay link for the HV-supply?
